- Abstract
- We designed a weld monitoring system with UV and IR sensors using a embedded DSP controller for implementing a distribution system ; running stand alone and communication with outside by industrial standard protocols. Also this system provided a USB port in order to be acquiring data in PC. The user interface program in PC visualized the IR and UV data in time, frequency and state space. A correlation of IR and UV signals showed closely related to weld signal at an interval represented a welding width and depth. Through these results, we proposed a monitoring algorithm for a integer type DSP.
